The new pen has another type of temperature sensor type that my old station cannot handle.

So the decision to make an new station was not hard to make 🙂

The withe connector is for power and fan power to the smoke sucker ( like a vacuum cleaner with carbon filter).

Each port holds a indication ring that is lights up for channel select and status.

Bottom view, the bottom plate will hold the H-Bridge converter.

Three channel H-bridge with extra filter, this enables me to set a constant voltage over the soldering pen instead of pulsed. Pulsed power can be achieved if I find it useful for some reason.

Update

After some testing and probing I found out that the WMRP pen has electronic interface which means I have to get my hands on a station that can handle that pen, and then probe and try to find the data command to get temperature data out from the sensor inside. So because I do not have any station that can handle the pen, since then I have not worked anymore on the station. I hope I can get my hands on a WMRP capable station so I can probe the commands. but until then…
This is mostly because I got hold of a Weller WSD161 that can handle two WSP80 pens at the same time, before I only had a Weller EC2001 (25w pen).

Why Version 2, where is the Version 1 ?

Yes I did a version 1. It only needed a bit more code before it was working alright, but as usual I had to much to do and too lite time at the moment. And when I finally had some time it was more fun to make a Version 2 instead.

I bought a none working station and only kept the case. The transformer could not handle 2 x 80w pens so i had to fit a much larger transformer in the same place as the old, quite hard to fit in the case 🙂
